Application filed December 1, 1924. Serial No. 753,182.

To all whom it may concem:

Be it known that I, WALTER S. LAKE, a citizenof the United States, and a resident of Kansas City, county of Jackson, Stateof Missouri, have invented a certain new and useful Improvement in Belt Fasteners, of which the following is a complete specification.

This invention relates to belt-fasteners and my object is to reduce a belt-fastener which may be readi y and easily insrted and secured inposition, and which i use will provide a completely flexible hinge connection that will ass over belt pulleys without subjecting t em to unusual wear or knock.

Anotherobject is to produce a fastener of such construction that the pull on opposite ends of a belt will be exactly counterbalanced, this construction leading tea lengthening in the life of the belt.

A further object is to produce a fastener which may be conveniently sold in rigid form, but which uponapplication to a belt will immediately recover its flexible nature and provide a hinge connection for adjacent ends of a belt.

A' still further object is to provide a strong, durable, efiicient and inex ensive belt-fastener, rimarily intended or; use with the belt-ihstening machine illustrated and described in m copending applications forPatents, Ser. 0. 603,620, filed November 27 1922, and Ser. No. 659,522, filed August 27, 1923; and in order that the invention ma be fully understood, reference is to be ha to the accompanying drawing, in which Figure 1 is a top plan view of a fastener embodying the invention as it will appear after being secured on a belt.

. Figure 2 is an edge view of the same,-

Figure 3 is a top plan view of the fastener. Figure 4-is a section on the line IV-IV of Figure 3.

Figure 5 is a plan view of the hinge pin.

Figure 6 is a plan view of one of the fastening laces.

Figure 7 is a side elevation of one of the laces.

In the said drawing, where like reference characters identify corresponding parts in all of the figures 1 indicates a pivot pin which is formed th a series of equi-space reduced circumferential portions 2.

roughout its length with in one of the reduced portions, 2,..which are i of such width as to snugly receive the looped and interlocked wire laces, and then said looped portions are crimped to reliably secure them in position against dislodgment either longitudinally of the pin or longitu- 1 dinally of each other (see Figure 3).

As soon as all of the reduced portions 2 at the pin 1 have been equipped with lacin wires, the fastener is preferably secure rigidly n the position shown in Figure 3, by treating 1t with a light coat of any suitable adhesive or cement (not shown). In

this connection it is to be noted that the pivot pin 1 is formed with projecting ends 6 for reception in the belt-fastening machine pifdmy copending application above-identi- The device as a unit (held by the cement) is inserted in the belt B by the use of the machine, the inclined hooks 5 being readily pressed through the belt from the top side thereof, andupon contact with the base of the machine are crirnped as shown in dotted lines in Figure 2. It will be apparent when the-belt is mserted in operative position, that immediately it passes over a pulley, the adhesive or cement securing the fastener in fixed relation, will be ruptured, the parts then bein freed for operation as a hinge.

-With t e fastener of the invention, referi'ing particularly to Fi re 1, it will be noted that the pull exerted y each wire lace is exactly counterbalanced by the pull of its companion lace, and this is due to the fact that the force exerted by each lace is diametrically opposite that of its companion lace. This result is accomplished due to the interlocking of the laces, as distin ished from a construction in which the pulfiin adjacent ends of the belt is oil center with respect to each other. It will be readily apparent that if the force is equally applied along the whole width of the belt at its adjacent ends, the wear on said belt due to fricill tion will be equally distributed over the entire wearing surface; as distinguished from an uneven pull at one pointleading to a rapid wear and deterioration at that point.

From the above description it will be apparent that l have produced a device of the character described which possesses all of the features of advantage set forth as desirable, and while I have described and claimed the preferred embodiment of the same, I reserve the right to make all changes properly falling within the spirit and scope of the appended claims.

I claim: I

l. A belt fastener comprising a pivot in, and a plurality of metallic laces arrange in pairs and pivotally secured to and extending in o osite directions from said pin, the opposed aces of each pair being arranged to apply their pulling strain at diametrically opposite sides of said pin.

2. A. belt fastener comprising a pivot pin, a pair of metal laces looped midway their lengths and interlocked and applying pressure on the pivot pin at diametrically opposite sides and. extending in opposite directions, each lace comprising a pair of straight portions having belt-engaging hooks and lying in the same horizontal plane, the straight portions of the opposed laces being in longitudinal alinement.

3. A wire belt lace looped midway its length and twisted and terminating in a pair of belt-engaging points and a pair of straight portions, the points respectively and the straight portions respectively being parallel and in the same plane and extending in the same direction.

a. A belt fastener comprising a pivot pin, and a plurality of metallic looped laces, said laces being interlocked and arranged in pairs on opposite sides of and pivotally engaging the pin, the looped portion of each lace being adapted to apply its pull on the pin at a point diametrically opposite that of its war panion lace, and each lace terminating in a pair of hooks adapted to engage the belt at points in alinement with the hooks of its companion lace.

5. A belt fastener comprising a ivotpin formed with a plurality of reducei circumferential portions, and a plurality of metallic laces, said laces being interlocked and arranged in pairs on opposite sides of and pivotally engaging the pin within a reduced portion, the looped portion of each lace being adapted to apply its pull on the pin at a point diametrically opposite that of its companion lace, andeach lace terminating in a pair of books adapted to engage the belt at points in alinement with the hooks of its companiondace.

6. A belt fastener comprising a pivot pin, and a plurality of metallic laces arranged in pairs and pivotally secured and cemented to and extending in oposite directions from said pin, the opposed laces of each pair being arranged to apply their pulling strain at diametrically opposite sides of said pin.

in witness whereof I hereunto a my si 1 ature.
